The offer runs from Monday at 00:00 GMT to Thursday at 23:59 GMT. A minimum deposit of $20 with code MBOX gets 1 Mystery Box minigame.
The bonus is redeemable once per day. Free spins come out of the Mystery Box at random: 25 to 100 spins per box. The code MBOX applies at deposit, and it's the same code every time.
Spins work on slots only. Wagering is 50xB.
The offer expires on 2026-10-29. It suits players who deposit regularly during the week and want a daily shot at extra spins; that's the whole mechanic.
